- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Be consistent in quoting.

MAJOR cleanup of the Bmake framework.
This includes removing all vestiges of the old not-really supported
ability to build cross tools targeting non-FreeBSD systems, such as
m68k Lynx and NetBSD. Move as much duplicated code from platform
Makefiles into the shared Makefiles. Add a simple mechanism for
specifying ELF 'ldscripts'. Also share as many .h files as possible
(now a single bfd.h vs. one per platform).

Updated Bmake framework for Binutils 2.15.

Properly quote the lib path.

Stage 3 of dynamic root support, con't.
'ld' should also search /lib for dynamic libraries.

s/x86_64/amd64/g where possible.

Add elf_i386_fbsd emulation.
